SIGHT FOR FIREARMS.

I My invention relates to the type of sights for' firearms in which thewedge is used to position the sight at the desired elevation and myinventlon consists 1n improvements which make said type effective andpracti-' cal instead of ineffective and of doubtful utility as said typehas been heretofore. Heretofore with sights of this type the Wedgepositions the sight at an unknown elevation and a stranger to thefirearmcannot use it eflectively while with my invention I provide for agiven make and caliber of rifle the sight may be adjusted back and forthin shooting until the amount of rise shall have been determined andthen, as in the form shown for example, the proper notches to correspondmay be made in the bottom of the wedge and thereafter wedges so notchedwill be installed on every such rifieias it leaves the factory and itwill reach the hands of the purchaser in shape for instant and effectiveuse of any range Within its practical limits. In other words I providelimits forthe movement of the wedge so that without taking ones eye fromthe object aimed at one can count'the clicks as the wedge passes alongthe barrel and can thus determine ust what position of elevation thesight will be in. Another means of indicating the position of elevation.consists in a scale which at a glance will indicate the position ofelevation.

In the drawings: Figure 1 is a plan of a sight .embodying'my invention;Fig. 2 is a sectional elevation of the same; Fig. 3 is a section on line3-3 of Fig. 2 on a larger scale; Fig. 4c is a partial section on line4-4 of Fig. 2; Fig. 5 is a partial section on line 5 -5of Fig. 1; andFig. 6 illustrates a modification.

Barrel A is in dove-tailed connection with the end a of spring member a,the latter havinga sight at a The spring member is slotted at a and hastwo semi-circular bear ing porti ns a Mounted to slide along the barreland within slot a is the rackwedge member B having teeth to engagecorresponding teeth .on the pinion B which is mounted'on shaft .6,the-latter carrying the Specification of Letters Patent.

Application filed September 26. 1913. Serial No. 792,047.

cylindrical portion 6 which is substantially flush with the adjacentbearing portion a, so that the scale on portion b may be easily read inconnection with the mark a on the adjacent bearing portion a.Turn-button D 18 provided to turn the shaft and pinion B. Pin 6 isrigidly fixed to the barrel and is adapted to engage notches in thebottom of the wedge member B, each of the end notches e having its outerwall substantially vertical and intermediate notches 6 being alsoprovided. When the pinion B is rotated the rack member B is moved tochange the elevation of the sight and it can ride over the pin 6 becauseof the yielding of the spring sight member which furnishes the bearingfor the pinion, and the rack member B can move in either direction incase the pin 6 engages one of the notches 6 but; the movement is limitedby the end notches e because of the vertical walls above described. Ifdesired a pin F may be provided on the portion 7) to ride in a slot f inthe adjacent bearing portion and this provides a convenient means forlimiting the movement of the rotary member and therefore-the wedgemember in both directions.

In Fig. 6.1 show the toothed portion of the rack member B curved and inthis case the notches on the bottom of the wedge member are spaced apartequally, thus giving varying amounts .of elevation of the sight forequal amounts of rotation of the gear, while it will be observed that inthe form of Fig. 2 the space between the two rear notches is less thanbetween the next two and so on, it being desirable to have thisincreasing distance .of travel on account of the increasing drop as thebullet progresses.

I provide a groove 6 in the bottom of the wedge to engage web e andthereby assist the guiding of the wedge member.

In using my device it will be clear that the operator may rotate thepinion and thereby move the rack member until it reaches the limit ofits movement in either direction and then the pinion may be rotated andas the wedge member passes over the pin 0 the operator can tell by thefeeling and by hearing and independently of 111s vision just whatposition the wedge member occupies and therefore what the elevation ofthesight is,and this is of the utmost importance in the use of firearmsparticularly for hu ting purp ses.

tion of the rack member carrying the teeth curves from the rightdownwardly and then upwardly and the drop is provided for sighting atvery short distances, say up to 50 yards or thereabout while at thatdistance the sight is preferably raised, the rise beginning when thefalling of the bullet compensates for the difference between the line ofsight and the axis of the bore, this form of curve being preferable incases where the firearm is to be used for sighting at very shortdistances as well-as long distances and both the lowering and theraising being accomplished by' rotationof the gear continuously in onedirection.

I have disclosed an operative surface of the wedge member in which oneportion slopes downwardly and another upwardly but my inventioncontemplates an operative surface in which portions are inclined to eachother whether downwardly or upwardly or otherwise.

What I claim is:

1. A- sight for firearms comprising a spring member carrying a sight; awedge member movable to change the elevation of the sight; rotary meansto movethe wedge; and means including said spring member when the latteris moved in the direction of its resiliency toward and fromanother-portion of said last mentioned means to indicate the position ofthe sight to the user independently of his vision, said indicating meanspermitting rotation of the rotary member in either direction.

2. A sight for firearms comprising a spring member carrying a sight; awedge movable to change the elevation of the sight and having a seriesof notches; means to reciprocate the wedge; a pin to engage the seriesof notches and hold the wedge in the desired position; and means tolimit the movement of the wedge in both directions of reciprocation. y

3. A sight for firearms comprising a barrel having a pin; a springmember carrying a sight and provided with a bearing; a gear with ashaft, said shaft being mounted in said bearing and having a turn buttonat one end; a wedge member engaging said gear and reciprocated therebyalong said barrel and having on its under surface a series of notches,one of the end notches engaging said pin to limit said movement ofreciprocation in one direction and holding the wedge member in thatposition and the other end notch engaging said pin to limit saidmovement of reciprocation in the other direction and hold the wedgemember in that position, and the remainder of said series of notchesengaging said pin as desired to hold the wedge in the position desiredbut permitting movement of the wedge member when desired in eitherdirection.

4. A sight for firearms comprising a sight member; a wedge member with acurved toothed surface; and a gear to engage said curvedsurface and movesaid wedge to give varying amounts of elevation of the sight for equalamounts of rotation of the gear.-

5. A sight for firearms comprising a spring member carrying a sight; awedge member whose movement changes the elevation of the sight and whichis adapted to reciprocate; means to reciprocate the wedge, said meansengaging said springmember; and means acting automatically under theinfluence of said spring member to hold the wedge in the desiredposition of its travel. p

6. A sight for firearms comprising a spring member carrying a sight; awedge member movable to'ehange the elevation of and means actingautomatically under the influence of said spring member to hold thewedge in the desired position.

8. A sight for firearms comprising a sight; a gear to move said wedgemember;

sight member; a wedge member having portions of its surface inclined toeachother; anda rotary member to move said wedge to change the elevationof the sight, rotation of said rotary member in one directionlowh eringand then raising the sight member.

9. A sight for firearms comprising a spring member carrying a sight;"awed e movable to change the elevation of t e sight; rotary means to movethe wedge;

means to limit the movement of the wedge;

and means to indicate to the user independently of hisvision the amountof movement from such limit, a portion of the limiting means being alsoa portion of the indicating means.

10. A sight for firearms comprising a spring sight member having abearing portion; a wedge member movableto change the elevation of thesight; a rotary member to move said wedge member and mounted in saidbearing and having an extension outside of said bearing; and meansindependent of said extension to hold the wedge in the desired position.
